Could you, pls, reenable 652a8a0838b38a6eab85c55fc61cedd1c61ef20f
temporarily? Then recompile Emacs, and run

--8<---------------cut here---------------start------------->8---
# emacs -Q -l tramp --eval '(setq tramp-verbose 10)' /ssh:some-host:/etc/somedir/file.yaml
--8<---------------cut here---------------end--------------->8---

Try to edit the file. When the problem appears, return control by
C-g. Show the resulting *debug tramp/ssh some-host* buffer. Likely, it
is large; you could send it to me directly.
